10G stackable fiber aggregation switch for enterprise networks
This 10G aggregation switch is a high-performance distribution base for subordinate access switches and offers the highest operational efficiency and reliability. Its full configuration of 20 SFP+ ports (10G) – including 4 mGbE (1G/2.5G/5G/10G) combo ports – and FleX uplink ports with up to 200G uplink capacity guarantees flexibility and investment protection. In addition, the professional PSU redundancy, hot-swappable fan modules and backplane stacking of up to 400G bandwidth ensure fail-safe operation. Management is automated via the LANCOM Management Cloud (SD-LAN) or via Web-GUI and CLI.

Flexible network topologies
The LANCOM XS-6128QF is an ideal aggregation instance for the networking of access switches. Depending on the size of the installation, it integrates into the network topology either on the top level as core switch facing the WAN (2-tier design) or on the second level as distribution switch between a core switch and the access switches (3-tier design).

TCO-optimized design
The design concept of the LANCOM XS-6128QF provides for a very low total cost of ownership (TCO), because all ports are natively available, which saves a costly modular design. So this aggregation switch enables all maximum port options out of the box with combo downlink (copper/fiber) and combo uplink (25G/40G) fiber ports. All ports are industry standard, even for stacking, so there is no need for costly proprietary cables. For example, there is the option of using SFP+ modules in the 4x 25G SFP28 ports for up to 4 additional SFP+ ports. Decentralized stacking thanks to the possibility of using standard short and long range modules is also possible with this model.

State-of-the-art multi-Gigabit performance on all ports
The LANCOM XS-6128QF offers extremely strong port performance and unmatched port flexibility through its future-proof fiber-optic FleX ports. This makes it the perfect foundation for fail-safe networks that can cope with the increasing demands from IoT, mobile devices, and cloud applications. 20 SFP+ ports (10G), 4 of which can be used as multi-Gigabit Ethernet (mGbE) combo ports, serve as a high-performance distribution instance for building switch structures. Enormous backhaul capacity is available via either 2 QSFP+ (40G) or 4 SFP28 (25G) high-speed uplink FleX ports. Non-blocking backplane stacking via 4 SFP-DD FleX ports (50G) ensure "line-speed" switching without latency. Ideal for virtualized applications and use as a higher-level campus switch in very large, distributed enterprise networks. If uplinking or stacking is not required, the front FleX uplink ports can be used as either 4x 10G/25G or 2x 40G downlink ports, and the rear SFP-DD FleX ports can be used as 4x 25G downlink ports for aggregating access switches.

Flexibility and investment protection thanks to LANCOM fail-safe stacking
The LANCOM fail-safe stacking feature keeps your network flexible and your investment secure. Stacking makes child’s play of expanding your network, as several physical switches combine into a single logical unit for convenient maintenance and management. When you expand your network, the new switch automatically receives a configuration from the stack master and is ready to use within seconds. Furthermore, device or network redundancies can be implemented with stacking for maximum reliability. With the LANCOM XS-6128QF, stack processing with a separate backplane CPU remains independent of network load thanks to four dedicated SFP-DD-FleX ports (50G).

Maximum operational security
The LANCOM XS-6128QF can be operated with up to twohot-swappable PSUs (power supply units). This allows a quick and uninterrupted replacement of defective power supply units. Front-to-back airflow design with swappable fans improves cooling in 19-inch racks and extends the product lifetime. Stacking is a major contribution to highly resilient scenarios.

Configurable access control
The LANCOM XS-6128QF stops rogue clients from gaining unauthorized access to the network. This is ensured by secured access control on all ports as per IEEE 802.1X (port-based, single, multi, and MAC-based) or by ACLs (access control lists).

Full layer 3 functionality
The LANCOM XS-6128QF is capable of performing layer 3 tasks such as DHCP server functionality, i.e. IP address management, or the predefinition of network routes across one or more network segments. Thanks to dynamic routing, the switch can also react quickly to network changes. The optimal route for data traffic within the network is thus constantly redefined by the LANCOM XS-6128QF based on the load level. This results in a load reduction on the router, so that these capacities are then additionally available for handling external data traffic and increase the efficiency of the entire network.

Cloud-managed LAN and switch stacking
With the LANCOM Management Cloud, the XS-6128QF offers quick and easy network integration as well as automatic provision of the configuration across locations with the a click of a mouse. Cloud-managed LAN replaces the configuration of individual devices and enables automatic assignment of VLANs
to switch ports. Cloud-managed switch stacking also enables convenient management and monitoring of the entire stack. Learn more in the Design guide switch stacking.

Secure remote management
Secure communication protocols such as SSH, SSL and SNMPv3 mean that the LANCOM XS-6128QF is ideal for the professional management of remote networks. The switch also supports the TACACS+ protocol for authentication, authorization and accounting. This optimized solution promises maximum security for multi-site network management and monitoring.

Security "made in Germany"
As a holder of the "IT Security made in Germany" trust mark, LANCOM has also committed to keeping its products free of secret backdoors. This makes the LANCOM switches ideal for operation in sensitive environments and always in accordance with General Data Protection Regulations (GDPR).

Secure Terminal Access
This function provides access to the command line of the LANCOM switch ("CLI tunneling") directly from the LANCOM Management Cloud—encrypted and without leaving the cloud interface. Be it trace or ping commands for rapid troubleshooting, access to low-level configuration parameters and detailed statistics in the LCOS SX operating system, or secure remote access to third-party devices in the local network via the integrated SSH client—Secure Terminal Access offers expert functions and extensive diagnostic and troubleshooting commands on your devices.

LANCOM Limited Lifetime Warranty (LLW)
This enterprise switch is reliably covered ex factory by the LANCOM Limited Lifetime Warranty. Regardless of the switch's operating time, the warranty is valid until the End of Life status of the device (max. 10 years).
